Removal and Installation

CAUTION:

The rotation direction indicated in the text is as viewed from the engine front.

NOTE:

When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spilling.

REMOVAL

1. Remove front wheel and tire (RH) using power tool.
2. Remove front fender protector (RH).
3. Drain engine oil.

CAUTION:

• Perform this step when engine is cold.
• Do not spill engine oil on drive belt.

4. Drain coolant.
5. Remove the following parts.

• Intake manifold.
• Drive belt.
• Rocker cover.
• Water pump pulley.

6. Support the bottom surface of engine using a transmission jack, and then remove the engine bracket and insulator (RH).
7. Set No. 1 cylinder at TDC of its compression stroke:

    a. Rotate crankshaft pulley (2) clockwise and align TDC mark (without paint mark) (A) to timing indicator (1) on front cover.

(B) : White paint mark (Not use for service)

    b. Check the matching marks on each camshaft sprocket are positioned as shown.

(1) : Timing chain

(2) : Camshaft sprocket (EXH)

(3) : Camshaft sprocket (INT)

(A) : Matching mark (Peripheral groove)

(B) : Pink link

(C) : Matching mark (Peripheral groove)

• If not, rotate crankshaft pulley one more turn to align matching marks to the positions.

8. Remove crankshaft pulley:

    a. Secure crankshaft pulley (1) using suitable tool (A).

    b. Loosen and pull out crankshaft pulley bolt.

CAUTION:

Do not remove the bolts as they will be used as a supporting point for the pulley puller.

    c. Attach Tool (A) in the M 6 thread hole on crankshaft pulley, and remove crankshaft pulley.

(B) : M6 bolt

Tool number : KV11123000 ( - )

    9. Remove front cover:

    a. Loosen bolts in the reverse order as shown.

    b. Cut liquid gasket by prying the position ( ) as shown, and then remove the front cover.

    10. Remove front oil seal from front cover using a suitable tool.

CAUTION:

Be careful not to damage the front cover.

    11. Remove chain tensioner (1):

    a. Fully push down the chain tensioner lever (A), and then push the plunger (C) into the inside of tensioner.

•  The tab (B) is released by fully pushing the lever down. Then the plunger can be moved.

    b. Pull up the lever to align its hole position with the body hole position

• When the lever hole is aligned with the body hole position, the plunger is secured.
• When the protrusion parts of the plunger ratchet and the tab face each other, both hole positions are not aligned. At that time, correctly engage them and align these hole positions by slightly moving the plunger.

    c. Insert the stopper pin (D) into the body hole through the lever hole, and then secure the lever at the upper position.

    NOTE:

A hexagonal wrench of 2.5 mm (0.098 in) is used as a stopper pin (D).

     d. Remove chain tensioner.

    12. Remove the timing chain tension guide (2) and the timing chain slack guide (1).

    13. Remove the timing chain (2).

• Pull the timing chain slack toward the camshaft sprocket (EXH) (1), and then remove the timing chain and start the removal from camshaft sprocket (EXH) side.

CAUTION:

Do not rotate crankshaft or camshaft while timing chain is removed. It causes interference between valve and piston.

    14. Remove the crankshaft sprocket and the oil pump drive related parts:

    a. Remove oil pump drive chain tensioner (1).

• Pull out from the shaft (B) and spring attaching holes (A).

    b. Hold the top of the oil pump shaft using the socket (size: E8), and then loosen the oil pump sprocket nut and remove it.

    c. Remove the crankshaft sprocket (1), the oil pump drive chain (2), and the oil pump sprocket (3) at the same time.

    1. Install the crankshaft sprocket and the oil pump drive related parts:

    a. Install the crankshaft sprocket (1), the oil pump drive chain (2), and the oil pump sprocket (3) at the same time.

  : Engine front

• Install the crankshaft sprocket so that its invalid gear area (A) is toward the back of the engine.
• Install the oil pump sprocket so that its protrusion faces the front of engine.

NOTE:

There is no matching mark in the oil pump drive related parts.

    b. Hold the top of the oil pump shaft using the socket (size: E8), and then tighten the oil pump sprocket nut.

(1) : Crankshaft sprocket

(2) : Oil pump drive chain

(3) : Oil pump sprocket

    c. Install oil pump drive chain tensioner (1).

• Insert the body into the shaft (B) while inserting the spring into the attaching hole (A) of cylinder block front surface.

    c. Put a paint mark (B) on crankshaft pulley, mating with any one of six easy to recognize angle marks (A) on crankshaft bolt flange (1).

    d. Turn another 60 degrees clockwise (angle tightening).

• Check the tightening angle with movement of one angle mark.

    10. Check that crankshaft turns smoothly by rotating by hand clockwise.

    11. Installation of the remaining components is in the reverse order of removal.

INSPECTION AFTER INSTALLATION

• Before starting engine, check oil/fluid levels, including engine coolant and engine oil. If less than required quantity, fill to the specified level.
• Use procedure below to check for fuel leakage.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leakage at connection points.
• Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration.

NOTE:

If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after hydraulic pressure rises.

• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids including engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to specified level, if necessary.
• Summary of the inspection items:

Item		Before starting engine	Engine running	After engine stopped
